WORST PRODUCT I HAVE EVER BOUGHT- and I’m NOT picky.
Color: Black, Color: Black
DO NOT BUY. Genuinely the worst product I have ever bought. I’m not a picky person. But upon receiving this bag, I immediately felt iffy about the material of the bag. Then I opened it to get a whiff of a rancid fishy smell. As I’m not a picky person, and it was $20, I moved past these two immediate issues. My problem came on day 4 when the interior ripped. The material is so cheap it was not able to be sewn to be fixed. I was irritated, but was able to move on from even this. Day 6 of use was the final straw for me. The zipper got caught and completely stuck on the ripped material. While trying to wiggle it, the tab to pull the zipper came off. While again trying to get it open by hand, the zipper ripped completely open and part of the zipper track came off. This is THE MOST DISAPPOINTING ITEM I HAVE EVER BOUGHT. Absolutely DO NOT RECOMMEND. DO NOT GET THIS BAG. I don’t even want to give this one star.

SO MUCH SPACE AND IS SO CUTE
Color: Black, Color: Black
I LOVE this bag. To give you an idea, yeah duh it’s cute whatever. BUT let me tell you I brought this to an all day race event and fit my (large) wallet, 2 pairs of sunglasses, all of my lippies, AND NOT ONE BUT TWO FULL BOTTLES OF COKE!!! And it still zipped. Insane amount of space in this thing and it’s so cute too. 10/10 would recommend and I’m buying it in the khaki color too!

Cute & stylish
Color: Dark Black
Purchased this clutch for a Christmas event. It was compact, stylish and made heads turn. I loved it. I was able to fit a slim wallet, a lipstick, my max pro phone and some gum. The color was great - I ordered the black with gold. And for the real reason I bought it - the fact that it is similar to a major brand but paid nowhere near that, made it all worth the price.
